Civilian Belt-Fed vs the Legendary M249 SAW | Forced Reset Trigger + FightLite MCR

Published on August 15, 2025
Duration: 39:18

This video provides an in-depth comparison between the legendary M249 SAW and the civilian-accessible FightLite MCR equipped with a forced reset trigger. It details performance evaluations including barrel changes, reloads, accuracy bursts, and extensive heat mitigation testing. The analysis highlights key differences in operating systems, heat management, ergonomics, and component design, offering insights for enthusiasts considering high-capacity firearm platforms.

Quick Summary

The M249 SAW, an open-bolt machine gun, offers superior heat mitigation compared to the closed-bolt FightLite MCR, a forced reset rifle. While the MCR can achieve higher cyclic rates with its FRT trigger, the SAW's design is better for sustained fire. The MCR's barrel handle can become dangerously hot, impacting barrel changes.

Frequently Asked Questions

What are the main differences between the M249 SAW and the FightLite MCR?

The M249 SAW is an open-bolt machine gun, while the FightLite MCR with an FRT trigger is a closed-bolt forced reset rifle. Key differences include heat mitigation (SAW superior due to open bolt), barrel change ergonomics (SAW superior), and cyclic rate (MCR potentially higher).

How does the forced reset trigger (FRT) affect the FightLite MCR's performance?

The FRT trigger allows the FightLite MCR to achieve a higher cyclic rate, mimicking some machine gun capabilities. It offers three positions: safe, semi-auto, and forced reset mode, providing rapid semi-automatic fire.

What are the heat management implications of the MCR's closed-bolt design compared to the M249 SAW's open-bolt design?

The M249 SAW's open-bolt design allows heat to escape more easily, reducing cookoff risk. The FightLite MCR's closed-bolt system traps more heat, leading to higher chamber temperatures and a greater potential for cookoff under sustained fire.

Are there any significant ergonomic issues with the FightLite MCR compared to the M249 SAW?

Yes, the FightLite MCR's barrel handle can become extremely hot, hindering quick barrel changes. Additionally, the charging handle placement on the left side can make locking the bolt to the rear difficult, especially with an ammunition source attached.

What is the approximate cost of a FightLite MCR setup similar to the one in the video?

A fully kitted-out FightLite MCR, including the upper, lower, FRT trigger, optic, and bipod, can cost just under $10,000. This price point is comparable to a similarly equipped AR-15 or a precision rifle setup.
